Low power rotation compressor

ABSTRACT

A low power rotation compressor includes a base, a rotation disk, a piston structure, and a casing. When the rotation disk is rotated, the piston structure is moved by rotation of the rotation disk, to co-operate with the cylinder structure and the slide-way, to press the air contained in the air collection container of the casing into the pressure storage container of the casing, thereby producing a required pressure simultaneously. Thus, the low power rotation compressor may use a low power motor to obtain a higher pressure and a higher air exhaust rate, thereby increasing the efficiency and decreasing the cost.

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a low power rotation compressor, and more particularly to a low power rotation compressor that may use a low power motor to obtain a higher pressure and a higher air exhaust rate, thereby increasing the efficiency and decreasing the cost.

[0003] 2. Description of the Related Art

[0004] A first conventional compressor in accordance with the prior art is a reciprocating type compressor which uses the principle of the crank axle to drive the piston to move reciprocatingly, and to co-operate the cylinder to squeeze the air and oil, so as to produce the pressure. However, the conventional reciprocating type compressor needs to use a higher power motor to obtain a higher pressure, thereby consuming time and energy, and thereby producing noise during operation.

[0005] A second conventional compressor in accordance with the prior art is a helical type compressor which uses the principle of the helical rotation to squeeze the air and oil in the helical pipe, so as to produce the pressure. However, the conventional helical type compressor needs to use a higher power motor to obtain a higher pressure, thereby consuming time and energy, and thereby producing noise during operation.

[0006] A third conventional compressor in accordance with the prior art is a vane type compressor which uses the principle of the fluid dynamics of the vane to produce the pressure during rotation of the vanes. However, the conventional vane type compressor is available for the working environment at a low pressure, and cannot be operated at a high pressure. In addition, the conventional vane type compressor easily produces noise during operation.

DETAILED DESCRIPTION OF THE INVENTION

[0024] Referring to the drawings and initially to FIGS. 1-3, a low power rotation compressor 1 in accordance with a preferred embodiment of the present invention comprises a base 10, a rotation disk 20, a piston structure 3 0, and a casing 40.

[0025] The base 10 has a body 11 having an inside formed with a hollow receiving space 111. The body 11 of the base 10 has a bottom formed with a circular hole 112 communicating with the receiving space 111. The receiving space 111 of the body 11 of the base 10 has a top opening provided with an enlarged annular flange 12 which has a periphery formed with multiple through holes 121. The bottom of the body 11 of the base 10 is provided with a protruding sleeve 13 communicating with the circular hole 112 of the body 11 of the base 10.

[0026] The receiving space 111 of the body 11 of the base 10 has an inside provided with a slide-way 14 which is in turn formed with a first slope section 141, a rising section 142, and a second slope section 143.

[0027] The rotation disk 20 includes a disk body 21, and a pivot shaft 22 combined with each other. The pivot shaft 22 of the rotation disk 20 is protruded from a bottom of the disk body 21, and may pass through the circular hole 112 of the body 11 of the base 10, so that the disk body 21 of the rotation disk 20 may be received in the receiving space 111 of the body 11 of the base 10. In addition, the disk body 21 of the rotation disk 20 has a periphery provided with multiple cylinder structures 23. Each of the multiple cylinder structures 23 is formed with a through hole 231.

[0028] The piston structure 30 includes a spindle 31, a spring 32, an extension rod 33, two piston rings 34, and a wheel disk 35. Each of the two piston rings 34 is mounted on a periphery of the wheel disk 35. The spring 32 is mounted on the spindle 31. The spindle 31 has a bottom formed with a mounting hole 311 for mounting the extension rod 33. The spindle 31 has a top formed with a threaded portion 312, and the wheel disk 35 has a bottom formed with a screw bore 351. Thus, when the spindle 31 is extended upward through the through hole 231 of each of the multiple cylinder structures 23, the threaded portion 312 of the spindle 31 may be screwed into the screw bore 351 of the wheel disk 35, so that the piston structure 30 may be mounted in each of the multiple cylinder structures 23 of the disk body 21 of the rotation disk 20 to perform a reciprocating movement therein.

[0029] The casing 40 is substantially disk-shaped, and is mounted on the enlarged annular flange 12 of the base 10. The casing 40 has a surface provided with an air collection container 41, and a pressure storage container 42 located opposite to the air collection container 41. The air collection container 41 of the casing 40 has an inside formed with a hollow air collection chamber 411, and has a periphery formed with an air inlet 412 communicating with the air collection chamber 411. The pressure storage container 42 of the casing 40 has an inside formed with a hollow storage chamber 421, and has a periphery formed with an air outlet 422 communicating with the storage chamber 421.

[0030] The casing 40 has a periphery formed with multiple through holes 41 aligning with the multiple through holes 121 the enlarged annular flange 12 of the base 10, so that the casing 40 may be secured on the enlarged annular flange 12 of the base 10 by multiple bolts that pass through the multiple through holes 41 of the casing 40 and the multiple through holes 121 the enlarged annular flange 12 of the base 10.

[0031] In assembly, the piston structure 30 may be mounted in each of the multiple cylinder structures 23 of the disk body 21 of the rotation disk 20. Then, the disk body 21 of the rotation disk 20 may be entirely received in the receiving space 111 of the base 10, and the pivot shaft 22 of the rotation disk 20 may pass through the circular hole 112 of the base 10. Then, the pivot shaft 22 of the rotation disk 20 is provided with multiple ball bearings 50 and belt wheels 60. Finally, the casing 40 may be mounted and secured on the enlarged annular flange 12 of the base 10 by the multiple bolts that pass through the multiple through holes 41 of the casing 40 and the multiple through holes 121 the enlarged annular flange 12 of the base 10.

[0032] Referring to FIGS. 3 and 4 with reference to FIGS. 1 and 2, the motor (not shown) may drive the belt wheel 60 and the pivot shaft 22 of the rotation disk 20 to rotate the rotation disk 20, so that the piston structure 30 may be moved by rotation of the rotation disk 20, and may co-operate with the cylinder structure 23, to carry the air contained in the air collection chamber 411 of the air collection container 41 of the casing 40 into the receiving space 111 of the base 10.

[0033] When the piston structure 30 is moved to the slide-way 14 of the base 10, the extension rod 33 is rested on and pressed by the first slope section 141 of the slide-way 14 of the base 10, to push the wheel disk 35 upward, so that the wheel disk 35 may be pushed and lifted during rotation of the rotation disk 20. When the piston structure 30 is moved to the rising section 142 of the slide-way 14 of the base 10, the air contained in the cylinder structure 23 may be fully pressed into the storage chamber 421 of the pressure storage container 42 of the casing 40, thereby producing a pressure simultaneously. When the piston structure 30 is moved to the second slope section 143 of the slide-way 14 of the base 10, the piston structure 30 may be returned to its original state by the restoring force of the spring 32.

[0034] Thus, the rotation disk 20 may be rotated continuously to perform the above-mentioned procedures successively, so that the air and pressure may be conveyed into the storage chamber 421 of the pressure storage container 42 of the casing 40 successively.

[0035] It is appreciated that, each of the cylinder structures 23 has a small size, and rotation of the rotation disk 20 may produce an inertia effect, thereby reducing consumption of the whole power efficiently. Thus, the rotation disk 20 may be rotated by a motor having a lower power, and may achieve the purposes of obtaining a higher pressure and obtaining a higher air exhaust rate. In addition, the compression velocity of the low power rotation compressor 1 in accordance with the present invention is ten times of that of the conventional compressor.

[0036] Referring to FIG. 5, for obtaining a greater air exhaust rate and a greater pressure, the cylinder structures 23 may be arranged on the surface of the disk body 21 of the rotation disk 20, and the slide-way 14 in the receiving space 111 of the base 10 may be widened.

[0037] The principle of compression of the low power rotation compressor 1 in accordance with the present invention is described as follows.

[0038] In general, the rotation disk 20 is provided with 6 to 12 cylinder structures 23. Each of the cylinder structures 23 has a small size, and has a diameter of about 2 to 10 centimeters and a depth of about 2 to 5 centimeters. The rotation disk 20 may be rotated by a motor having a lower power. By such a design, when the rotation disk 20 is rotated through a cycle, the 6 to 12 cylinder structures 23 may transmit the pressure to the pressure storage container 42 of the casing 40.

[0039] Assuming that the diameter of the rotation disk 20 is 30 centimeters, and the rotation disk 20 is provided with 12 cylinder structures 23 each having a radius of 3.5 centimeters and a depth of 3 centimeters. Thus, the air exhaust rate of the rotation disk 20 every cycle may be calculated as follows.

[0040] The air exhaust rate of each of the cylinder structures 23 is equal to:

3.5 cm(radius)×3.5 cm(radius)×3.1416(π)×3 cm(depth)=115.5 cm ³(cubic centimeters).

[0041] The total air exhaust rate of all of the 12 cylinder structures 23 is equal to:

115.5 cm ³×12=1386 cm ³=1.386 liter.

[0042] If the operation speed of the motor is 800 rpm (rotation speed per minute), the air exhaust rate per minute is equal to:

800×1.386 liter=1080.8 liter.

[0043] If the operation speed of the motor is 1000 rpm (rotation speed per minute), the air exhaust rate per minute is equal to:

1000×1.386 liter=1386 liter.

[0044] If the operation speed of the motor is 1500 rpm (rotation speed per minute), the air exhaust rate per minute is equal to:

1500×1.386 liter=2079 liter.

[0045] In comparison, the operation speed of the motor of the conventional compressor is about 2200 rpm. The conventional compressor belongs to a high power compressor, but the air exhaust rate and the pressure obtained by the conventional compressor is much smaller than that of the low power rotation compressor 1 in accordance with the present invention.

[0046] Thus, the low power rotation compressor 1 in accordance with the present invention may use a lower motor power to obtain a higher pressure, thereby enhancing the versatility thereof.

[0047] Accordingly, the low power rotation compressor 1 in accordance with the present invention has the following advantages.

[0048] The conventional compressor has to use a high power motor to obtain a higher pressure and a higher air exhaust rate. Relatively, the low power rotation compressor in accordance with the present invention may use a low power motor to obtain a higher pressure and a higher air exhaust rate, thereby increasing the efficiency and decreasing the cost.

[0049] The low power rotation compressor in accordance with the present invention has a smaller size and simpler construction, and may be assembled easily, thereby facilitating assembly and maintenance thereof.

[0050] The low power rotation compressor in accordance with the present invention may use a low power motor, thereby reducing noise during operation.

[0051] The number of the cylinder structures may be adjusted according to the user's requirement, so as to obtain a higher pressure and a higher air exhaust rate.
